I went hunting for the oldest Robominer/GT trading statement that I could find and I found
this one which dates from January 8th 2009. There are some very interesting observations:
1. I think this is a demo account.
2. The opening balance was 10K and both pairs were started at one mini

This is way over leveraged. The recommended lot size for a 10K start on both pairs (using a balance factor of 3500) is 0.02.
3. Despite the fact that, even now, the account is still over leveraged, the account is doing well. $17,608.33 balance, s/b lot size 0.05
4. There are five open trades, all AUDNZD from Jan 12th and Jan 13 whose
rollover 
fees/swap now exceed any potential profit.
5. $7,608.33 in profit as I write this
